Reaction Mechanism: Draw a reasonable reaction mechanism (i.e. show the electron movement) for the synthesis of 2-butoxynaphthalene.
The Al2O3 does not react. If the sample residue weighs 2.456 g, what is the mass fraction of Fe2O3 in the original sample?
the exhaled air contains 6.2% H2O and 15.3% O2 by volume. How many moles of H2O are expelled from the body each minute? How many moles of O2 are absorbed by the body each minute?
We add excess Na2CrO4 solution to 16.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.380 grams.
A typical popcorn kernel has a volume of .250 mL and contains 1.114 mg of water. The kernel will pop at a temperature of 170 C. What is the pressure in atm inside the kernel right before it explodes?
Use the ideal gas law to calculate the concentrations of nitrogen and oxygen present in air at a pressure of 1.0 and a temperature of 298 .
